CVE-2021-29775Network attack vector

Credential disclosure via Web UI script injection

Published Jun 28, 2021 · Updated Sep 16, 2024

Cross-site scripting in IBM automation products allows remote authenticated users to execute JavaScript in the Web UI and disclose credentials. The Web UI renders user-supplied content containing embedded JavaScript without adequate neutralization; IBM has not identified the affected field or handler. A valid user session is required to plant the script, which changes trusted-session content and can expose credentials.
